show error message after running Jetracer code

running Jetracer code and show error message as below, please kindly help

Hi goodeyedeer,

Thanks for reaching out!

This issue is caused by an operation that is not available in PyTorch 1.1. Could you try upgrading to PyTorch 1.2? You can find the installation instructions here

Alternatively, If you install torch2trt from master, it should also resolve this issue (non-existent PyTorch operations no longer cause hard failures). You can find it here

Please let me know if you have any questions.
